Hi folks. I've taken a little time recently to go macro hunting, and while doing that I noticed what I think are three different software floating point implementations in gem5. There is ext/fputils which has support for 80 bit floats, arch/arm/insts/fplib.hh and .cc which I'm assuming ARM uses, and ext/softfloat which RISCV uses.
I can't think of a good reason for us to need three different solutions to the same problem. Is there a good reason for this, or was each just not aware of the others? Can we fold one (or two) of these into a preferred implementation and get rid of the extra(s)? Gabe
